Consuming events

• Events may need to be ``blocked'' from reaching objects sometimes
  • In password entry, keystrokes need to be caught by the application but not reach the Text object for display
  • A GUI builder might use mouse clicks to select objects such as Button, but not activate the Button
• The delegation model allows this for key and mouse events
• Events are discarded by calling the method Event.consume()
